Calibration of Pressure Measuring Equipment 3ABSTRACTThe report evaluates the two different methods utilised in measuring the pressure and calibrationin Thermodynamics. The two devises used for this experiment to measure the pressure areconnected to affixed deadweight calibrator. The objective is to analyse the linearity and accuracyof the two set of devices that were used in performing the experiment. The report talks in detailabout the procedure used in calibration of the equipment for the purposes of improving itsaccuracy.
Calibration of Pressure Measuring Equipment 4CHAPTER ONE1.0IntroductionPressure given conventionally obtained by the formula P = F / A, is defined as the forcethat acts normal to an object’s surface area per unit area. The experiment involved measuring thepressure variable by utilizing two devices- “TH2 Apparatus”. The apparatus contain two deadweights and a calibrator that is connected to the pressure measuring devices- “Bourdon PressureGauge” and the “Electronic Pressure Sensor Device”( Maul, 2005, pp. 781-782). For use of theequipment to be effective, it is necessary for priming of the same equipment (Agrawal, 2008).When the equipment are primed before use, their accuracy and linearity of measurement of theexperiment improves greatly. The equipment is cleaned using a special equipment in thelaboratory followed by their calibration so as to ensure that the measurement during theexperiment are taken correctly (Avison, & Barham, 2014, pp. 09007). The figure below is an illustration of experiment setup. The TH2 equipment is used forcalibration of pressure. It compares the theoretic value of pressure to the experimental value. Theaccuracy ratio should not be more than 3:1 between the equipment and the theoretic value. Theequipment utilizes weights that are put on the equipment to create pressure since pressure=force/area. The area is the place where the weight are placed then the force is obtained from;Force=m*a where a=gravitational acceleration. The different pressures that are known and fixedfrom the weights placed on the equipment (deadweight) are generated. The characteristics of theunit including the linearity and accuracy are then determined by use of a Bourdon pressure gaugeand an electronic pressure sensor.
